Subject [jira] [Commented] (HBASE-15411) Rewrite backup with Procedure V2
Date Fri, 25 Mar 2016 22:44:25 GMT

    [ https://issues.apache.org/jira/browse/HBASE-15411?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15212530#comment-15212530
] 

Ted Yu commented on HBASE-15411:
--------------------------------

Here are the existing Util classes in hbase-client:
{code}
hbase-client//src/main/java/org/apache/hadoop/hbase/client/RegionReplicaUtil.java
hbase-client//src/main/java/org/apache/hadoop/hbase/client/ResultStatsUtil.java
hbase-client//src/main/java/org/apache/hadoop/hbase/exceptions/ClientExceptionsUtil.java
hbase-client//src/main/java/org/apache/hadoop/hbase/ipc/IPCUtil.java
hbase-client//src/main/java/org/apache/hadoop/hbase/protobuf/ProtobufUtil.java
hbase-client//src/main/java/org/apache/hadoop/hbase/quotas/QuotaTableUtil.java
hbase-client//src/main/java/org/apache/hadoop/hbase/security/EncryptionUtil.java
hbase-client//src/main/java/org/apache/hadoop/hbase/security/SaslUtil.java
hbase-client//src/main/java/org/apache/hadoop/hbase/security/SecureBulkLoadUtil.java
hbase-client//src/main/java/org/apache/hadoop/hbase/zookeeper/ZKUtil.java
hbase-client//src/test/java/org/apache/hadoop/hbase/exceptions/TestClientExceptionsUtil.java
hbase-client//src/test/java/org/apache/hadoop/hbase/ipc/TestIPCUtil.java
hbase-client//src/test/java/org/apache/hadoop/hbase/security/TestEncryptionUtil.java
hbase-client//src/test/java/org/apache/hadoop/hbase/security/TestSaslUtil.java
hbase-client//src/test/java/org/apache/hadoop/hbase/zookeeper/TestZKUtil.java
{code}
I don't think the waiting logic should go to any of the above class.

Maybe create hbase-client/src/main/java/org/apache/hadoop/hbase/client/AdminUtil.java ?

> Currently full / incremental backup is driven by BackupHandler (see call() method for
flow).
> This issue is to rewrite the flow using Procedure V2.
> States (enum) for full / incremental backup would be introduced in Backup.proto which
correspond to the steps performed in BackupHandler#call().
> executeFromState() would pace the backup based on the current state.
> serializeStateData() / deserializeStateData() would be used to persist state into procedure
WAL.
